1
Q

What are the different types of spontaneous intracranial haemorrhages?

A

SAH
Intracerebral
Intraventricular

2
Q

What is SAH?

A

Bleeding into the SAH
Usually underlying berry aneurysm
Sometimes AVM
Trauma

3
Q

What is the clinical presentation of SAH?

A
Sudden onset severe headache
Collapse
Vomiting
Neck pain
Photophobia
4
Q

DDx of sudden onset headache

A

SAH
Migraine
Benign coital cephalgia

5
Q

What are the signs of SAH?

A

Neck stiffness
Photophobia
Decreased conscious level
Focal neurological deficit (dysphagia, hemiparesis, 3rd nerve palsy)
Fundoscopy; retinal or vitreous haemorrhage

6
Q

What is the initial investigation in a suspected SAH?

A

CT scan

7
Q

What will an LP show in SAH?

A

Bloodstained or xanthochromic CSF (6-48 hrs)

8
Q

How is cerebral angiography performed?

A

Seldinger technique via femoral artery

Digital subtraction

9
Q

What is the gold standard in SAH?

A

Cerebral angiography/ CTA

10
Q

Why can cerebral angiography miss an angiography?

A

Vasospasm; all patients with SAH will be give nimodipine

11
Q

What are the complications post SAH?

A
Re-bleeding
Delayed ischaemic deficit
Hydrocephalus
Hyponatremia
Seizures
12
Q

What can be done to help prevent re-bleeding in SAH?

A

Endovascular techniques

Surgical clipping

13
Q

When does delayed ischaemic neurological deficit tend to occur?

A

Days 3-12

14
Q

What can be done to help prevent delayed ischaemia?

A

Prevent vasospasm; nimodipine

Triple H therapy; hypervolaemia, hypertensive, daemodilation

15
Q

What is the treatment for hydrocephalus?

A

CSF drainage via:
LP
EVD
Permanently; shunt

16
Q

What can cause hyponatremia?

A

SIADH

Cerebral salt wasting

17
Q

Do you fluid restrict for hyponatremia in SAH?

A

NO; supplement sodium intake or give fludrocortisone

18
Q

Is the seizure risk increased acutely and post SAH?

A

Yes; some will give anticonvulsant prophylaxis

19
Q

What should the initial treatment and investigations be in SAH?

A
Bedrest
Analgesia
Anti-emetic 
IV fluids
CT scan brain
LP
Refer to neurosurgeons
20
Q

What is the commonest cause of intracerebral haemorrhage?

A

Secondary hypertension

21
Q

What is the pathogenesis of hypertensive ICH?

A

Charcot-bouchard microaneurysms arising on small perforating areas

22
Q

Which area of the brain is most commonly affected by hypertensive ICH?

A

Basal ganglia and internal capusle

23
Q

What is the presentation of an ICH?

A

Headache; not as sudden onset or as severe as SAH
Focal neurological deficit
Decreased conscious level; increased ICP leads to reduced CCP

24
Q

What are the recommended investigations of an ICH?

A

CT scan; URGENT if decreased GCS

Angiography if suspicion of underlying vascular anomaly

25
Q

What is the treatment of an ICH?

A

Surgical evacuation of haematoma +/- treatment of underlying abnormality
Non-surgical management; if haemorrhagic stroke refer to stroke team

26
Q

What is the prognosis post ICH?

A

Good; if small superficial clot

Poor; if large basal ganglia or thalamic clot with major focal deficit or deep coma

27
Q

When do intraventricular haemorrhages occur?

A

Rupture of subarachnoid or intracerebral bleed into a ventricle

28
Q

Where will blood tend to pool in intraventricular haemorrhages on CT?

A

Occipital horns of lateral ventricles

29
Q

What can AVMs cause?

A

Seizures
Haemorrhage; ICH, SAH, subdural
Headache
Steal syndrome

30
Q

What is the treatment for AVMs?

A

Surgery
Endovascular embolisation
Stereotactic radiotherapy
Conservative
